How Ultrasonic Energy Enables Cutting and Hemostasis | EziSurg Medical

In modern minimally invasive surgery, precision, efficiency, and safety are critical. EziSurg Medical's easyUS™ Ultrasonic Dissection and Hemostasis System represents a cutting-edge innovation in energy-based surgical technology. But how does ultrasonic energy actually work in converting mechanical vibrations into effective cutting and hemostasis during surgical procedures?

 

What Is Ultrasonic Energy in Surgery?

 

Ultrasonic energy refers to high-frequency mechanical vibrations—typically around 55.5 kHz in surgical systems like EziSurg Medical's easyUS™—that are transmitted from a piezoelectric crystal in the handpiece to the active blade. These vibrations are beyond the range of human hearing but powerful enough to disrupt tissue at a microscopic level.

 

When ultrasonic energy is applied to tissue, it produces mechanical motion and heat, resulting in two major surgical effects: cutting and coagulation (hemostasis).

 

How Is Ultrasonic Energy Converted into Cutting?

 

The cutting mechanism of the ultrasonic dissection and hemostasis system is based on mechanical vibration. The vibrating blade of the easyUS™ device moves longitudinally at a frequency of 55.5 kHz, creating friction against the tissue. This motion breaks down cellular structures and allows the blade to slice through soft tissue with minimal force.

 

Unlike traditional electrosurgical methods that rely on electric current, ultrasonic cutting is purely mechanical. This allows for precise dissection with less lateral thermal spread, reducing the risk of collateral damage to surrounding tissues.

 

How Is Hemostasis Achieved with Ultrasonic Energy?

 

Hemostasis, or the process of stopping bleeding, is equally important during surgery. The easyUS™ system achieves hemostasis through coaptive coagulation. As the vibrating blade compresses the tissue, mechanical friction produces localized heat, which denatures proteins and seals small blood vessels (usually up to 5 mm in diameter).

 

Key hemostatic features of the EziSurg Medical ultrasonic system include:

 

Efficient vessel sealing: Reliable closure of small and medium-sized vessels.

 

Real-time feedback: Automatically adjusts power output based on tissue type and thickness.

 

Tissue grasping capability: Enhances compression and improves coagulation effectiveness.

 

Ultrasonic hemostasis is not only effective but also smoke-free and electrically neutral, minimizing the risk of electrical burns and providing a clearer surgical field.


Advantages of EziSurg Medical's easyUS™ Ultrasonic System

 

EziSurg Medical's easyUS™ platform combines precision engineering with advanced energy control to deliver consistent surgical results. Here's what sets it apart:

 

Versatility: Suitable for a wide range of procedures, including laparoscopic, gynecological, and thoracic surgeries.

 

Ergonomic handpiece: Lightweight design improves surgeon comfort and maneuverability.

 

Enhanced patient safety: Reduced thermal spread and no electric current through the patient.

 

Cost-effectiveness: Durable instruments and reliable performance lower overall procedure costs.

 

In comparison to traditional monopolar or bipolar systems, the ultrasonic energy system offers a dual-function tool—simultaneous cutting and hemostasis—streamlining the surgical workflow and reducing instrument exchanges.

 

Applications in Minimally Invasive Surgery

 

EziSurg Medical's ultrasonic dissection and hemostasis system is widely used in:

 

Laparoscopic cholecystectomy

Colectomy

Gynecological procedures

Thyroidectomy

Bariatric surgery

Thoracoscopic lung resections

 

Thanks to its precise energy delivery and efficient vessel sealing, easyUS™ helps reduce blood loss, minimize operative time, and enhance surgical outcomes.

 

The Future of Ultrasonic Surgical Energy

 

As the field of energy-based surgical technology continues to evolve, innovations like EziSurg Medical's easyUS™ platform are redefining what's possible in operating rooms. With its smart feedback system, robust dissection ability, and reliable hemostasis performance, ultrasonic energy is becoming the preferred choice for surgeons worldwide.

 

EziSurg Medical remains committed to advancing surgical excellence through innovation, safety, and sustainability.
